It's supposed to work. However, I'm having reports of dual 7450 with
1G or 1.5G of RAM locking up, I haven't been able to track those down.
Is this an Apple machine ? The 7450 has a bug that prevents use on
SMP with HW hash table walk. Apple is supposed to implement a HW
workaround for this on their machines, but if it's not an Apple machine,
then you may have to implement software TLB load.
